Currently, the domestic nursing information system software products are being developed competitively with the participation of many companies, generating quantitative development with high value added. However, it is true that the study that concurrently adds qualitative enhancements to such quantitative development has been inadequate. In order to secure international competitiveness in the field of nursing information system software, it is necessary to establish quality requirements on this system, and along with it, establish an evaluation system on the nursing information system software products. The purpose of this study is to analyze the accompaniment and technology of the nursing information system, and by identifying the requirements, establish test and evaluation system of the said system.

This study starts from interests on an endeavor of each economy unit, especially the enterprises, for the survival and sustainability of themselves. Competition, how to get it, maintain it and advance it! Agreeing the perceivedness of industries, scholars and public; what the core competition of manufacturer is an competitiveness of product, this study focuses on the PLM system as the key solution for obtaining the competitiveness of product with reviewing the contents and studies of PLM formulated. PLM is highlighted as the one of top tier ICT solution for the product development domain of manufacturing industry today. First of all, this study deals with the opinion of actual work-site and management of our small&medium business for the benefits of PLM based on product development; the impact on the performances of management, which is the key objective of the existence of enterprises. In conclusion, the answers for these questionnaires shows positive perception of actual work-sites and managers for the PLM system. They agree some useful effects on shortening the term and downsizing the cost of product development due to Data integration and Process management, even if they have not full confidence on the effectiveness of the individual functionality of the PLM system.

The purpose of this study is to consider models for the production planning of multiproduct. Because these multiproducts use common facilities, labor, and materials, they are able to be considered jointly instead of planned independently. Initially linear programming models will be considered, followed by some examples of modeling and analysis when the cost structure is nonlinear. Basic model components are the following ; (1) inventory balance equations for each product to link successive time periods, and (2) capacity constraints for each period to represent resource limitations.

A reactive piloting policy for Flexible Assembly Lines (FAL) is proposed, where the sequencing of the operations as well as the assignment of tasks to manipulators are not predetermined but driven by the actual state of the FAL For all work-in-process coming from a manipulator, the next destination is determined by minimizing a temporal criterion taking into account the time needed to reach the destination, the load of the manipulator to reach, the durati on of the operation to be completed in the destination manipulator, and the availability of product components in this manipulator. The purpose of proposed piloting policy is to manufacture a given quantity of products as rapidly as possible by balancing the amount of work allocated to manipulators and to reduce the efforts required for scheduling the production of short series of diversified products. After introducing the characteristics of assembly processes and FAL modelization, the proposed algorithm is evaluated by simulations. The simulations of the proposed algorithm showed satisfactory results.

The usability evaluation of the remote fluid monitoring device, which was introduced to reduce the work of nurses and increase the efficiency, was performed due to the expansion of the non-face-to-face medical system. Remote fluid monitoring is a fusion of various technologies such as fluid measurement and analysis, error correction technology, and transmission technology. The range of use by users, the information they want to obtain, and the control device, etc. are wide, and the factors that evaluate the product are also diverse. Therefore, it is difficult to improve the product through evaluation. In this study, a quantitative index was developed to help improve the product for commercialization by conducting 20 usability evaluations in three areas of product stability, operability, and satisfaction with the remote sap monitoring system device. It was performed through infrared and load cell-type sap monitoring devices. In terms of stability, there was a difference in installation work such as fixing the pole of the device, and high satisfaction was shown for operability and accuracy. In terms of product satisfaction, the satisfaction of load cell devices was generally high.

IT 기술이 발달함에 따라 저전력, 초소형 센서노드를 설치하여 무인으로 정보를 얻을 수 있는 시스템의 도입이 점차 확대되는 추세이며, 이것을 위하여 온도, 습도, 가스 등 환경정보를 획득할 수 있는 센서뿐만 아니라 초소형 저전력 복합환경센서 ROIC(Read-Out Integrated Circuit)의 중요성이 증가하고 있다. 또한 휴대폰, 노트북, 스마트폰, 태블랫 PC 등의 모바일 IT 제품들은 빠르게 소형화, 슬림화, 저전력화 되고 있다. 이런 시스템의 요구에 따라 음향부품도 기본적인 음향감지/출력 성능 이외에 크기 및 소모전력이 중요한 기능요소로 크게 부각되고 있으며, 이것을 위하여 소형화, 저가격화가 가능한 MEMS(Microelectromechanical Systems) 음향센서 및 ROIC 개발이 요구되고 있다. 따라서 본고에서는 복합환경센서 ROIC 및 MEMS 마이크로폰 ROIC의 기술동향 등에 대해서 고찰하고자 한다.

The majority of database users interact with database systems by manipulating forms. This paper discusses the fundamentals underlying forms and considers low these mechanisms affect the behavior of forms We then review the forms supported by commercial products. None of the packages reviewed provide all of the features that make up an ideal form. We propose a new design that overcomes many of the limitations observed in the packages currently available. The new system is event- driven, object-oriented, supports a hierachy of composite blocks, and is primarily modeless. Forms are defined as top-level blocks and blocks can be either atomic or composite structures with methods directly included in their definition. Messages are passed among form objects. Defining forms with the proposed system is simple because from definitions are similar to type declarations in Pascal.
